Abstract

N-Cubylmethylnormorphine (1) and N-cubylmethylnoroxymorphone (2) have been synthesized and found to be more potent ligands at the μ and κ opioid receptors than morphine and oxymorphone respectively. In the guinea-pig ileum preparation, compounds 1 and 2 were characterized as opioid μ antagonists (Ke= 68 and 16 nM, respectively). Compound 2 also showed effective κ-antagonism (Ke= 22 nM). The narcotic antagonism ...
